American Museum of Natural History is an amazing adventure

Hello good or Ming 11/05/2019

Pseudo trash absolute garbage . You reject every notion that not all us are complete idiots who can not question your absurd stupidity you pass off as a scientific study of your dumb ass limited construct you make out to be reality .

Having teachers like her, learning wouldn't be a struggle for me

@@eclipse369. You sound intimidated. Just because she is passionate and studies something incredibly difficult, that you have no knowledge of, does not make her “ego too much”.

@@eclipse369. and you don’t know Jackie.

wisdom of this realm is foolishness to our creator.. #theawakeningisunstoppable and this is just regurgitated garbal wisdom and cgi...wake up

My favourite opinion.

PUT THIS ON THE NEWS! your fav girl is RIGHT!

Because nobody cares about Education, society is in ignorance of the factual truths and is developing an intellect in following fake-drama. Bad time for Education in the world.

The same reason why you are talking with your husband about the weather, how kids do at school or about the new neighbors. And not about Astrophysics... Btw. I despise scientists whose first sentence during a lecture is "Are you all exited?" and who wear more jewelry then the Kardashians on the red carpet.

...don't any of them bump into each other?!....

Thank god for youtube... did i just say that? lol But really, there are so many gems of up to date talks from scientists that we would never be privy to otherwise. The next best thing to hanging out with them.

wake up, earth is flat and stationary, space is a hoax, there is a firmament above us, people are waking up everyday.

@@godschild5587 God is probably very unhappy because you doubt HIS CAPACITY OF CREATING A GIANT UNIVERSE. You should be ashamed of trying to diminsh HIS WORK with this continuous effort,so you could feel special and important. At the moment ,you are NOT acting like a God´s child. You are acting like a VERY IGNORANT CHILD,ignoring God and His creation. The importance of people is not measured by the size of their body in the universe or the size of the universe around humans.The importance of people is measured by the capacity of accepting and recognizing how great is the Creator and His Creation. The Universe is Immense and His creator moves all over its extension. Deal with it.

@@billybelcaro9585 Unfortunately, there are people who make comments like the one I saw after yours.

Physics and lots of math will get you there.

@@lbpiercy It would be nice if someone occasionally answered any questions at all, though. ;-) I agree with you: the risk is that, missing good questions or answers, we assume that the questions we have matter and the answers given to them are correct.

@@lbpiercy "History shows science declares answers that are often later proven wrong." Uhu, and the thing that proves them wrong is more science, you fuckwit. Science, when it turns out to have been mistaken, will learn from its mistakes and build a new model that better fits the data we have. Religion just shuts its eyes and ears and screams "NAHNAHNAHNAH, CAN'T HEAR YOU!"

@@lbpiercy Never mind, you're right. My response was uncalled for.

Really? You envy them? Of what? Polluted and toxic planet? Thanks but no thanks. Think Fallout not Star trek. Toxic soil, polluted oceans, dirty rivers. Clean water will be more valuable than gold. Planet earth will be a wasteland in 200 years or sooner.

We ARE our predecessors' future generation.

freeze yourself

Galileo probably said the same thing.

Science can take blame for some of those things we do not know.

sure, "real"

Agreed. She's presenting to a diverse audience, not colleagues. Maybe all the haters here are Astrophysicists.

Agreed Robert. The lady's enthusiasm is infectious. She a true devotee of an important subject.

you feel like an 8 year old??

Thank you for making an excellent point. This stuff is NOT easy to understand!!

@@Blox117 I can't speak for Robert Stevenson, but I (a 55 year old man) do feel the excitement of an 8 year old learning this stuff. Which is a testament to her presentation ability. Even if you don't have an astronomy/cosmology background, you can still get as excited as a 3rd grader having your eyes opened with this kind of revelation, and I love how she ends it by saying that anyone can help with this analysis, anyone can open their inner scientist and experience the same kind of wonder that obviously drives her research. Well done.

Exactly. This was a beautiful presentation! I think the "fake news" comment just triggered the youtube trolls. LOL!

The usual men who cant stand a woman cos she doesn't go into all the mathematical shit they want to hear cos theyre losers with no imagination.

"Live hard, Die Fast Stars" ........like Jimi Hendrix/Janis Joplin and the rest of the 27yr old club

@MonkeyZorr Right..that's why there are so many of us are here commenting on her political jobs. lol

@Don Pelton, I agree, so many haters here. I enjoyed the hell out of this presentation, I'm over 60 but her enthusiasm made me feel like a kid again. These bozos are yawning and whining but I'm wishing it was 2 hours longer.

I'm not a child anymore.

There's the childishness! Ah... From the mouths of babes. @@CrimsonBlot

@@CrimsonBlot I'm sorry. I thought we were talking about mean spirited critiques.

That's just not true. The only question in question is global climate change an to the degree that man is responsible. That is about it. The rest of science is pretty safe. Stop exaggerating the idea that Liberals are 100% truth seekers and science observers while all conservatives believe in creationism. Science is about skepticism not consensus. Consensus is politics. Science is about trying to disprove what someone else believes to be true till after much peer review it is proven to be true or false. While maNy experiments can appear to show a theory is true it only takes one to prove it is not.

Why do some people reject even the most basic and well-established science truths? There are two sexes. Nuclear power produces no carbon emissions. GMOs are harmless. The ban on DDT has cost a million lives in Africa. A significant number of climate scientists have raised serious objections to the claims of the warmists. But some people believe their political fantasies are more important than facts.

Brian is right, it's absolutely pathetic that so many Liberals think they have the total right to "Science". That Conservatives just cannot comprehend or refuse to. It makes me vomit when Liberals behave so condescending.

Justin Hopkins, I detect a leftist who thinks science is God, and consensus is scripture. *"The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What are relevant are reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period." --Michael Crichton* Michael Crichton Lecture on consensus: web.archive.org/web/20050207040318/www.sepp.org/NewSEPP/GW-Aliens-Crichton.html

@@JayJay-ki4mi Science is a method, not a body of knowledge. I don't think anyone is a "science denier." The people who accuse others of being a "science denier" are usually the ones trying to pretend that their interpretation of the data (body of knowledge) is the only acceptable interpretation. They're the ones who think consensus is science.

Great advice, thank you.

Muslims defeat us and return us to the stone age. That's what the future holds.

My feelings exactly.

did it open up your eyes

@@2campercamper I never had the pleasure to meet a purple hippo, but that doesn't mean he is not of this world...you proof it. But to stay with the subject : it is not because you don't understand science and the "jargon" these two are not real , not observable, measurable, etc, etc. .The universe is measurable....but we have still to refine our means to do it. Patience is part of science.

@@2campercamper , Before you hit the reply tab, you should proof read what you write! Your first line shows that you can't even make a complete sentence. Maybe a basic English class wouldn't hurt you.

I was a bit familiar with the Gaia mission but not with Margulis' Gaia Hypo until I saw your post and investigated. After watching a thorough 10 part series "Voyage of the Continents" for many weeks at bedtime recently, I kind of drew the same conclusion of the hypothesis: It's as Earth is a living organism closely tied and evolving alongside what we deem life. Whether this is just a probable roll of the dice or intentional, well that is a whole 'nother topic :D Love your enthusiasm! Highly recommend that series.

looks like you are very proud? Pride is foolish. Downvoted. PS I like scientists, but I cannot comprehend PRIDE. I think it's some sort of illness. I would have understood if you had written 'it's so pleasant, I feel that my actions are so important for the humanity, and touching this well fills me with joy, and my fountain sparkles!'. I'll downvote any pride-filled turkey-cock.

But she says your laptop will be crashed.

Yes indeed! She is a splendid scientist. I wish her all possible succes in her carrier.

She's a waffling bore. I didn't hear any science, all I heard was planetarium marketing.

Silly-Ass BROAD Should Be In Front Of Third Graders

@@kneedeepinbluebells5538 I wish she was! Maybe then we'd have more kids becoming scientist, and not bible-thumping morons!

I love learning about space from a true maester of astronomy, I do hope she wont get killed off in season 8.

I wonder why most intelligent science people choose not to teach?

Important was a stretch

I, too, was surprised to hear that there are many "brown dwarf" stars near us which are too dim for us to see.

@@PersonalStash420 I would give you 10 "likes" if I could, you've said what we all think brother 😀👍

Telescopic perspective is still and real, but motion drawn from other perspectives is animated, based on calculated data to be processed in millions of years. (Years?) Since time doesn't exist, I have used the term Process for time, while year is the duration of the process of Earth rotation around Sun, which is just another process like numerous other processes, such as duration of cooking food in kitchen is different from the duration of process of a year. If you still think time exists, then think of vacuum or empty space, somewhere in the infinity, without any processes, where I would imagine duration of my cooking process, you would imagine a year on Earth and someone else would imagine drive from home to office, etc, etc but in fact, there were no processes to measure in vacuum or empty space somewhere in the infinity. Now its easier to think of Eternity (timelessness) in the Infinity (limitlessness) as well, where, Processlessness aare actually the Timelessness. Thanks for reading.

Brash aggressive style? Who's said anything about this? I see her as confident, talented, educational, tres knowledgable, passionate and an absolutely brilliant presenter. X P.s. also humorous and entertaining. X

EXACTLY !!

I know right.... Not nearly enough women have interest in something outside of a selfie; lunch with the girls.. .etc.... (So it seems anyway)... So yeah this is really a turn on lol..

@Welsh Simon you're not wrong.

@Benaiah Ahmadinejad word

I would like to see MY passion....on her face....lol

@@GabeTheGun1 I just like her cute voice

Indeed. Humanity may be a lost cause.

@Jerome Walker Habit mostly. Plus comments on channels like, ChessNetwork, Numberphile, and PBS Space Time, among a few others are generally better than the normal noise.

They are good for truthful criticism.

I fall into the same trap, Colin. I share the feels.

Ha ha ha exactly my friend. Curiosity killed the cat...

Pup314 Thanks for your thoughts. I had not considered time delay in visualizing these star positions. The presenter did not say whether her visualizations were corrected for time, that near stars are closer to their current positions relative to the sun and distant stars are billions of years from the positions we see them. I have spent a lot of time listening to scientific presentations and making them myself, though not on astronomy. I prefer to have each visual aid, like a graph, clearly explained, ordinate, abscissa, dimension, scale, trend lines, error bars, colors & symbols etc. In this case I kept feeling that the scale and resolution and the meaning of other characteristics of the images were left to my imagination. It can seem obvious to the presenter since they look at their data every day, but for most other people, taking time to explain what we are seeing is much appreciated. For example, early in the presentation I could not reconcile the apparent star burst pattern of bright stars which seems not to match the spiral distribution of matter in the galaxy. Could you explain for me what was being shown? Another question I had was later in the presentation of the distribution of iron rich stars represented in green. She said the more distant stars were bluer, so less iron and therefore older. But when she pulled back in the image of the galaxy, the green stars formed a starburst pattern in a small region of the galaxy. Is that because of the time factor you mentioned above. Thank you.

@@drmasroberts From what I understand the Kepler view was towards the constellation of Cygnus the Swan, and the stars we see are those stars in that direction we see from Earth. Kepler 2 mission after its gyroscopes had somewhat failed was allowed to look around the ecliptic for brief (compaired to the previous Kepler observation time) observations. So for Kepler 1 mission we are looking across a few spiral arms in a narrow area of view. Kind of like looking through a cardboard tube. we will see some near by objects and some medium objects and some distant objects in the field of view. I think (I am trying to understand this myself) the time dilation effect for the iron rich (green stars) compared to the distribution of the blue stars is not a major factor as the distances are in thousands and tens of thousands of years distant, and has more to do with concentration of super nova ejecta( heavier metalicitiy of stars formed from the super nova ejecta) towards the center of the galaxy. That sine more matter is closer in to the central black hole you will get heavyer stars that are both younger and live shorter lives, and enrich the instellar medium with heavier elements faster, as opposed to the outer rim and spirals of our galaxy where stars might be fewer in number smaller in mass on average, and thus longer lived and producing less heavy elements. I think, too, that locations of the actual spiral arms where matter is concentrated more also plays a part. I hope that helps you. I certainly do not know of all the variables in this scenario.

This is a question I've had for a long time now as well. As I hear about maps of the universe, I'm thinking that such maps are distorted by time delay. I have often wondered whether someone could construct a model of the universe, or our local area of the universe, that positions stars where we predict they should be now based on their velocity and trajectory. I've emailed several astronomers over the years with no reply to this question.

@@Knoxvilletim Maybe now with this Gaia star probe such information it gathers will make such a real time map possible? Maybe see if you can email the AMNH to find out the name of this presenter and take a look at the actual information and learn how to set it up yourself? Maybe star with the closes 10 stars to our Sun. some of shich would be Proxima Centauri, Alpha Centauri A, Alpha Centauri B, Barnard's star, to name 4 i can remember off the top of my head.

Hello. Can you, please, help me? I can't understand about gaps (9:18), when I'm blink on/blink off? What is this about?

Also, this is more of a teaser than a comprehensive explanation of the galaxy. If you want the details, there are plenty of people willing to give talks (and she might well be one of them) that last an hour or more. They may even be in the same building.

She makes me puke in my mouth a little.

​@@clevername8832 Why do you say that? We should appreciate scientists like her trying to motivate young people to marvel at the universe around us and to want to find out more. If we judge them by the way they talk or look, scientists like Stephen Hawking would have given up trying to interact with the public long ago.

What's all this doing for your everyday common man? With these billions spent, what's it concretely doing for us?

@@rogerdodger8415 Just compare the pittance (thousands or millions) allowed for basic science research compared to dropping untold billions on defense. I'm not saying that defense isn't necessary, just that congress willingly gives defense the lion's share of taxpayer's money and tosses 5% of that amount towards the science that not only educates humanity about the reality of their place in the cosmos (i.e. relieves their ignorance) but may also lead to new science and technologies that benefit mankind...you know, like in the past, the science research that led to COMPUTERS, SMART PHONES, the INTERNET, advanced agriculture to stave off the FAMINES of the past, advanced MEDICINE that prolongs and improves the quality of LIFE. Just because you may not stop and think about or be aware of these advances that ultimately behoove you doesn't mean that you should denigrate them out of your ignorance.
